I started my period around July 28 I am still bleeding today Aug 3 when are my most fertile days? Am I fertile now? I want a girl any tips?

Ovulation. The key to your fertility is when you ovulate. Not when you menstruate. All a period is is proof that you did not get pregnant during your last ovulation. You ovulate just shy of half way through your cycle. Thus in a 28 day cycle you ovulate days 13/14. Sperm, because they live for up to five days after ejaculation, cause pregnancy on any or all of the 5 days leading up to ovulation.
